Abstract

According to one embodiment of the present invention, a method for cross-service tagging is provided. The method includes creating connections to multiple applications, each application having multiple entities. Relationships are determined between the entities within a single application and between entities across multiple applications. A tag is associated with a selected one of the entities in a first one of the multiple applications. Entities in other applications besides the first application are identified that are related to the selected entity, based on the determined relationships. The tag is propagated across multiple applications by associating the tag with the identified entities in the other applications. According to a second embodiment of the present invention, a method for inferring tags suggestions is provided. This method includes analyzing email messages to create keywords from text analysis, from bringing content and tags from other email messages or directory applications. Tags suggestions from the various sources are merged and weighed according to an algorithm.

Description

BACKGROUND

The present invention relates to social tagging, and more specifically, to techniques for automatically generating and propagating tags in web 2.0 social networks and applications.
Managing the increasing volume of information available from various sources has become a challenging task for computer users. The adoption of Web 2.0 social networks and applications, where many users can create content, has increased this challenge. Over time, social tagging has developed as a non-centralized alternative to organizing and giving semantics to content and as a way of sharing organizational structure among all users of various applications. Using tags, users apply keywords to elements in the application, which serve to relate these elements to others sharing the same subject.
Social tagging serves a useful purpose because no single user would be able to manage the number of elements that normally populate a social application. Instead, every user visiting a web page or viewing a document has the chance to apply a tag, thus helping him and other users to search for it. This distributed intelligence is much more efficient than tagging by a single user. Examples of applications with social tagging include del.icio.us (social bookmarking); blogger.com (blogs), and virtually any current web 2.0, socially-oriented application.
The benefits of social tagging depend on the existence of a large enough user population that is inclined to perform the tagging effort, and also depend on there being enough tags to converge on a meaningful and stable set of tags. It has been estimated that it takes about 100 tags to reach a meaningful and stable set of tags.
Helping users manage the information available in email is also a growing challenge. For each message, a user must decide how to best categorize, mark, label, or remove important messages from the rest of the message to best facilitate later retrieval. Managing information in email currently primarily relies on manually filing messages into folders. Tagging has a benefit over folders in that a user can apply multiple tags to a single message without the message moving out of view, as is common in folders. Systems like Taglocity provide social tagging of email messages. When a user applies and shares the tag applied to a message, the recipient of the e-mail automatically gets the benefit of the tag applied by the former user into the message that was just received.

DETAILED DESCRIPTION

Embodiments of the invention provide ways to automatically propagate user-applied tags from one application to another across related entities belonging to different services, where relationships are discovered by the application itself.
As described above, social tagging has a number of advantages. However, there is a common problem in current social network technologies. In particular, though content can be related across these applications, and indeed mashups can be implemented to share content from one application to other, the added value of tags is not normally shared across applications: the semantics given by the classification applied by users must be repeated in each application.
For example, consider the social bookmarking application “del.icio.us” and the blogging application “Blogger.com”. Different users can independently post a bookmark pointing to a URL in de.licio.us, and publish a blog post announcing the discovery of an interesting URL in Blogger.com—the same link as posted in de.licio.us. Note that these two elements, the blog post and the bookmark, are obviously related, though they have no connection and thus represent two unrelated elements: not only are they of different nature and belong to different applications, but they lack semantics to help determine that they in fact represent the same thing (or a closely related one). If a user applied a tag on one of the two elements the other is not normally altered. Embodiments of the present invention leverage the user action of giving semantics to one element (tagging) in one application by making that connection available in other applications.
A related idea was developed in GroupMe!, (Abel, Henze & Kraus, “GroupMe! Where Information Meets”, poster paper in WWW2008, April 2008, China—http://www2008.org/papers/pdf/p1147-abelA.pdf). In GroupMe!, a user manually groups entities, belonging—to the user criteria—to related topics. The user can then apply tags to the group, and these tags get propagated to the entities it contains in their respective applications. Embodiments of the present invention differ from this work in part in that the grouping context provided does not need to be manually created. Instead, with embodiments of the invention, tags propagate to related systems via implicit relationships as bound by an email message, email thread, activity tree, or other set of structured information.
In some embodiments of the invention, a mechanism is created to aggregate tags from different social applications and merge the resulting set around related email messages. Additional embodiments of the invention expand this concept to: (a) function not only within email, but also in any other application where a mashup from other sources can exist; and (b) not only aggregate tags from other applications but also to propagate tags to other applications.
In general, embodiments of the invention extend application mashups to automatically propagate user-applied tags from one application to another across related entities belonging to different services, where relationships are discovered by the application itself. Usually applications provide an application programming interface (API) allowing outside applications to retrieve and update content. These APIs serve as a means to building a mashup. For any existing mashup allowing multiple applications to request content from or data sources through their APIs, embodiments of the invention allow tags to be sent (propagated) through the same APIs when an association exists between any two or more elements across applications.
One example that may be used to illustrate the invention is the situation of a blog post on blogger.com with links (URLs) to a few external websites. These URLs may have been bookmarked in del.icio.us, and may or may not, have tags on these bookmarks. Using embodiments of the invention, when a user applies a tag on the blog post, the blog application can apply these tags to the del.icio.us bookmarks.
Another example happens when a user receives an email with a URL in BlueMail (http://bluemail.almaden.ibm.com). BlueMail offers the ability to tag messages for easier organization and later retrieval, and indeed allows tags to propagate from a dogear bookmark if it exists. Using embodiments of the invention, when the user tags this email, the email client (or server) can propagate the tag to the dogear bookmark on that URL.
Furthermore, using embodiments of the invention, user tags can propagate through different services transparently to the user. These user-applied tags, which create “folksonomies” and add semantics to massively accessible items, would then propagate more broadly, thus enriching more content on more services than if a user had to manually select and apply tags to those entities.
The details of the implementation will vary accordingly to each mashup and the APIs used. While particular examples are described herein, it will be appreciated that the concepts illustrated herein can be implemented on virtually any mashup.
Various embodiments of the invention use the following elements:

- An application mashup bringing content from more than one source. For example, this may be an email client that interacts with blogging and social bookmarking applications.
- A way to discover and establish relationships among objects from those applications, which is described below in more detail. For example, from an email message with a URL a relationship can be established to the bookmark element in a social bookmarking application.
- The action of tagging one of the elements in the application. In some embodiments this may be done by a user, who applies a tag to help organize the contents he usually accesses, although other techniques are possible.

With the above three elements present, the mashup application will not only apply the tag(s) on the selected entity (in the previous example, on the email message the user is explicitly tagging) but it will also propagate the tag to the other services in the mashup through their APIs.
FIG. 1 shows a diagram of a system 10 for cross-service tagging in accordance with an embodiment of the invention. In this system 10, existing applications may include one or more blogging applications 12, social bookmarking applications 14, and email applications 16. Each of the applications includes an application programming interface (API) 18, 20 and 22 respectively. A cross-service tagging mashup application 24 includes a relationship discovery unit 26, and a tagging activity unit 28. The tagging activity unit 28 includes a tag initiation unit 30 and a tag propagation unit 32.
As mentioned above, the details for accessing each service will vary depending on each particular API. Also, how to get a service's contents and how to propagate tags will vary depending on each particular API.
How to establish relationships between the entities belonging to different applications, so that tags can be shared or propagated, will now be described. There can be several ways to do this. One way is URL matching. Whenever two entities point to the same URL there is clear connection between them. The URLs don't even need to be exact, but they can point to similar locations in the same server for instance. For example, the following might be considered as the same URL in terms of creating entities' relationships:

- www.myserver.com/news/november/tagging.html#footer
- www.myserver.com/news/november/tagging.html?printable=true
- www.myserver.com/news/november/

Text analysis is another way to establish relationships between entities belonging to different applicants so that tags can be shared or propagated. This may include tools like text-classifying algorithms that can be used to capture “similarity” among entities, regardless of whether they are the same class of elements or not (for example, comparing email messages' text to blog posts' contents). If they are found similar enough so as to be considered that they refer to the same objects or entities, then a relationship through which tags are propagated can be established.
In one example, tags may be pulled into email messages. Referring now to FIG. 2, there is shown a diagram of an example of pulling tags into email messages in accordance with an embodiment of the invention. A user 34 receives and is reading an email message 36, the email program queries for content related to the message on the related blogging 30 and bookmarking 40 (such as del.icio.us) applications. It is found that other users previously tagged a related blog post 42 as “research”, and a related bookmark 44 as “lotus”. The user 34 may then be presented the two tags “lotus” and “research” as suggestions for the incoming email message 36, or have these tags automatically applied by the system.
FIG. 3 shows a diagram of an example of pushing tags into email messages in accordance with an embodiment of the invention. If the user 46 categorizes his/her message 52, at the same time the email program propagates this tag to other elements (which are public) and may include a blogging server 54 and a bookmarking server 56, such as a del.icio.us server. In this example a tag for blog post 58 and a social bookmark 60 are automatically generated. Then, in one action several different entities, available to different users, have been enriched with semantics given by a single user. Users 48 and 50 reading content on the bookmarking or blogging application may then see the tag applied to the email message 52 even when they have no access to it. Similarly, tags may also be from social bookmarks. The blogging application 54 may discover the relationship between the URL bookmarked and a blog post mentioning the same URL. Then, at the time a del.icio.us user 50 tags this bookmark, the del.icio.us service 56 can automatically propagate the tag to the blog post 58 in the blogging server 54.
FIG. 4 shows a flowchart of a method 60 for cross-service tagging in accordance with an embodiment of the invention. In step 62, the cross-service tagging mashup application is connected to multiple applications. Relationships are then discovered between entities belonging to different one of the applications, in step 64. In step 66, a selected entity in one of the applications is then tagged. In step 68, entities in other applications related to the tagged entity are identified based on the discovered relationships. The tag may then be propagated to the related entities in the other applications, in step 70.
Embodiments of the invention directed to email applications pose special issues. For example, email messages are not universally shared with the public at large, unlike the popular web sites that feature tagging. Thus, to make tagging effective in the email context, is would be desirable to provide a way to easily apply tags to email messages within the much more limited number of users among which email is shared.
Embodiments of the invention may combine several different mechanisms for suggesting or automatically applying tags to email messages to help organize email for later search and retrieval. By making it easier and more efficient to associate tags with email messages, the use of tagging within email will be encouraged, enabling the user to enjoy its benefits. Embodiments of the invention may integrate several different approaches for associating tags with messages including one of the following (or combinations thereof):
leveraging prior tagging or indexing work on related messages
exploiting others' tagging work on shared or related messages
integrating analysis of the content of email messages to suggest meaningful tags for the message
leveraging tags from other sources on components of the message (such as the sender or pointers to web pages included in the message)
It will be appreciated that these concepts could be applied to applications besides email, such as any application that includes sharing information with a subset of users, such as shared document repositories or wikis.
Embodiments of the invention may combine several different mechanisms for suggesting or automatically applying tags to email messages. Fundamentally, these embodiments encourage more usage of tagging by making it easier and more efficient to associate tags with email messages. There at least three ways to make it easier to apply tags to email messages:
Automatically apply tags to email messages, thus obviating the need for any additional user effort. This approach makes the most sense when there is high confidence of the applicability of the tag to a message.
Suggesting or recommending tags for email messages, thus reducing the effort to apply the tag to the message to a single click or comparable lightweight user interaction. This approach presents the most salient tags to the user, but relies on the user to confirm applying the tag(s) to the message.
Applying a latent tag, so that the system associates a tag with an email message such that the tag can be useful in search, sort, or other information management techniques, but is not exposed to the user to avoid cluttering up the user interface. This approach can attach tags that could be useful in programmatic techniques for finding or sorting messages without burdening the user with more clutter or visual representation of the tags.
The goal of all of these approaches is to increase the number of meaningful tags applied to email messages, thereby increasing the scope of benefits enabled by tagging, while requiring a minimal amount of extra effort from the user to apply the tags.
An important aspect of some embodiments of the invention is to suggest or automatically apply relevant and useful tags to email messages. To do this, embodiments of the invention may use a combination of the above-described different approaches to help organize email for later search and retrieval.
One of these approaches is leveraging prior tagging. If the user has previously tagged an earlier message that is related to the current one, then that tag should be suggested or applied to the current message. A simple example illustrates this approach. If the user tags message A with a tag “foo”, if message B arrives that is a reply to message A, then tag “foo” is also probably relevant to message B. As another example, if a user has already filed a message into a folder, it may also make sense to tag the message with a label related to the folder name to enable searching and sorting by tag as well as by folder name. In this approach, we are leveraging user effort that has already been applied to the email message to either suggest or automatically apply tags to messages.
Another approach is exploiting others' tagging work on shared or related messages. This approach leverages other recipients' tagging work on a message to be shared with any other recipient of the message. Thus, if message C is sent to 7 people, and the first recipient tags it as “ProjectA”, then that tag could also be suggested to the other six recipients and the sender. This approach leverages the tagging work of any individual user to the others who are socially connected by sharing that message. This “social tagging” of email messages borrows directly from what happens in publicly shared Web 2.0 applications within the scope of email messages that are typically shared within a more limited scope of people.
Because sharing email messages is more limited, embodiments of the invention extend the scope of social tagging in email to make it more useful. For example, combining with the earlier approach of leveraging prior tagging, if message D is a reply to message C, then “ProjectA” could be offered as a tag to all the recipients of message D as a way of leveraging the effort of one person's tag of the related message C.
Another approach is integrating analysis of the content of email messages. A variety of methods (artificial intelligence, semantic data mining, etc.) have been used to identify keywords to represent the content of information. Examples of these methods include k-means or TF-IDF based text categorization, social-filtering, modified PageRank relation, latent semantic analysis, and neural network-based machine learning. These information clustering methods could also be used to suggest tags for email messages.
Another approach is leveraging tags from other sources on components of the message. As tagging has gained in popularity, more and more applications are offering tagging capabilities. For example, within IBM, Fringe allows employees to tag people with topics that are associated with those people. Del.icio.us allows tagging web page URLs with topics associated with the web page. Blogger.com allows blog postings to be tagged. By extension, URLs referenced in an e-mail might refer to a blog that is in turn tagged. Email is a very common communication channel that involves people and could be used to send pointers to web sites. Embodiments of the invention take advantage of the people and web pointers included in an email message and the tags associated with those artifacts to suggest that these tags might also be appropriate for the email message as well. In this way, embodiments of the invention take advantage of tags applied in other applications and use them to suggest tags for email, offering some integration of tagging across applications.
Perhaps the most flexibility and versatility comes from combining various approaches described above. For example, Artificial Intelligence (AI) techniques could identify that several threads of messages in an inbox share similar content. If a tag has been applied to any of those messages, the system could suggest that tag for any of the remaining messages. This combines leveraging prior tagging with analyzing the content of messages for similarity.
As another example, imagine person Alpha who has message E with tag “ProjectB” applied to it in her email store. At the same time, person Beta is about to read another message F. AI techniques could be used to identify that message E and message F are on a similar topic. Thus, by a combination of artificial intelligence techniques and social tagging, person Alpha's “ProjectB” tag on Message E will be suggested as a tag for message F to person Beta. In other words, suggesting tags other people have applied to similar messages, where similarity is given by some AI or semantic analysis algorithm.
At a more aggregated social level, applying artificial intelligence techniques to analyze a large body of tagged email data from a large number of people in the enterprise (perhaps scoped by business unit or job role) could identify relationships between specific tags and semantic concepts expressed in the text. Having arrived at this knowledge through analyzing data in the aggregate, the system could suggest a specific tag when it recognizes the semantic context in any email that is analyzed. This combination leverages social knowledge encoded in previous tagging behavior in the aggregate in a way that benefits individual users without actually having to share specific messages, but through shared semantic content from related messages.
Using all of the methods above may generate many ways of augmenting tagging on a message beyond what will be useful. Furthermore, the system needs to decide whether to automatically apply the tag, suggest it as a tag, or apply it as a latent tag. An algorithm may be used to rank which tags are most meaningful or likely to be useful and the most appropriate way to apply the tag to the message. Having a rank ordering of candidate tags is also useful for an interface that presents users a short list of suggested tags and if the user selects a tag to apply, which removes that tag from the short list and the next candidate in rank is added to the short list.
Embodiments of the invention may combine content analysis techniques, socially-based tagging, and the incorporation of related tags from other social software systems to produce categorization information which is presented to the user using a combination of means to consume them (automatically applied tags/folders, suggested tags/folders, search keywords). The advantage in this combination over the solutions listed above is that through providing a broader basis for suggestions, if any one dimension is lacking (e.g., not enough content for a good content analysis), the remaining sources may still provide a rich enough basis for suggestions.
FIG. 5 shows a diagram of a system 72 for augmented tagging in email in accordance with an embodiment of the invention. Assume that a new message arrives in a user's inbox. The message may be compared against the corpus of this user's e-mails using a Text Analysis algorithm 74, which produces a keyword set (A), shown as “bar baz” in FIG. 5. As part of the text analysis, a keyword extraction component 76 may use pattern recognition techniques pull out structured data such as URLs, file objects, people's names, etc. that are then used as seeds into other systems to gather social tagging information into a keyword set (B), shown as “foo xyzzy” in FIG. 5 (e.g., a URL is recognized and cross-referenced with del.icio.us to collect tags from the community).
The message may then be checked by the social tags component 78 for social tags, that is, tags that were already applied by other recipients of the message, and these are gathered into a keyword set (C), shown as “foo” in FIG. 5. A weight mixing function component 80 may then use a weight-based mixing algorithm to take as input the three keyword sets (A, B, and C) and aggregate the values into a single set of keywords which may be presented to the user in different forms:

- 1. As suggestions for tags to be applied to the message, as well as folders where the messages are to be moved. These are shown together with the message when the user opens it.
- 2. In the form of keywords that are not shown prominently for the users (in fact, they can be hidden altogether) but are used when the user performs a search.
- 3. Applied automatically in the form of tags, or by taking the action of placing the e-mail in folders matching the keywords (optionally bypassing the inbox altogether).

In order to facilitate the scenario above, the following techniques could be used. A text-classifier algorithm (A) can be run on the emails contents retrieving important keywords or other lexical tokens that can be suggested as tags. These keywords can also be combined with the users' existing and applied tag set to better match its own language. Text-classifying algorithms can also separate a population of data (messages) into categories or “clusters”, and this classification can also be used to grab tags that other messages in the same cluster have received to be offered as suggestions. Known solutions like TF-IDF based ones (used by SwiftFile), k-means or others could be used for this approach.
Another family of algorithms can gather socially-applied tags from applications outside of email to content embedded in the email message being analyzed (B). For example, an email with an embedded URL can trigger the search for tags applied in social bookmarking applications like del.icio.us, as each of them provide APIs or protocols to perform searches and retrieve information. This is the first embodiment of the invention as described above.
A person being named (or just being part of the recipients set) can be also queried to a corporate or social directory and the tags that person has received by other users can be retrieved (C). Like other web applications, directory applications offer a variety of protocols to retrieve users' information, including the tags that each user has received. For example, a user that has been tagged with the name of the project he works on would cause messages he sends to have that word as a tag suggestion.
These three categories can be combined too, as for example: embodiments may use the text classification algorithm (A), tags applied from other applications on components of the message (B), and tags applied to people associated with the message (C) create an abstract representation of the message content. That representation could be compared with representations of other messages that have been tagged. By transitivity, tags that other users have applied to similar messages (according to that abstract representation), can be used as suggestions for the incoming message.
FIG. 6 shows a flowchart of a method 82 of augmented tagging for emails in accordance with an embodiment of the invention. In step 84, a new email message is received by a user using an email application. The new email message is compared with previous emails sent to the user using a text analysis algorithm, in step 86. In step 88, a first keyword set is generated including words found in both the new and previous email messages. In step 90, a second keyword set is generated using social tagging information from another system besides the email application. In step 92 a third keyword set is generated using tags applied by other recipients of the new email message. In step 94, the first, second, and third keyword sets are aggregated into an aggregated keyword set using a weight-based mixing function. The aggregated keyword set is presented to the user, in step 96.
